abstract Many composites having a polymer matrix are obtained by physical modification. The aim of polymer physical modification is receiving its determined properties, mainly physical ones, by plastic state filler adding to the polymer. Obtaining required properties of the composite depends not only on the type of used filler but also its content, shape and adhesion on the boundary of polymer and filler. Glass fibres of E symbol are commonly used for polymer composites preparation. Determination of the influence of a glass fibre content and frequency on dynamical properties of polyamide 6 composite is the aim of this work. DMTA method was used to determine the influence of a glass fibre content and frequency on dynamical properties of polyamide 6 composite. Using this equipment, dynamical properties of polyamide composites in relation to the temperature and frequency were determined. Analysis of the influence of temperature and frequency on the conservative modulus and loss tangent has been performed. The relationship between the real modulus E’ and the temperature, at the frequency 1, 2, 5 and 10 Hz, is shown in Figures 1 and 2 shows the relationship between the loss tangent and the temperature at the frequency 1, 2, 5 and 10 Hz. Coefficient αT has been determined based on the WLF equation (Fig. 3).
